What does the aspect of a Time Controlled Signal typically include?

A Time Controlled Signal is designed to manage traffic flow at intersections or roadways in a specific sequence based on predetermined time intervals. The correct answer includes the aspect "Lunar White," which is typically used to indicate that a train should proceed with caution, often in scenarios where the signal may not be in the standard color sequence but requires attention. Lunar White can serve as an indicator for various situations, particularly in rail systems.

In the context of time-controlled signals, the focus is often on safety and the management of the traffic flow. While other colors like flashing red, solid yellow, and constant green serve important functions in controlling traffic and signaling actions to drivers, they are more commonly associated with traditional traffic control rather than the specific significance of a Time Controlled Signal aspect.

Understanding the distinct purpose of Lunar White as it applies to time-controlled signals emphasizes the variety of signal aspects that contribute to efficient traffic management, particularly in complex environments like rail crossing where additional caution is necessary.
